Why you should clean your solar panels?
There are many important reasons to keep your solar panels clean:
-
1. Preserving your solar panel's longevity - Solar PV systems are a long-term investment, lasting for decades if kept in working condition. Whether your panels are roof-mounted or ground solar installation, performance can be compromised if they are not properly maintained and cleaned regularly. Helping to prevent the build-up of grime and ensures the solar panel’s long-term benefits are maintained, maximising the return on your investment.
-
2. Maximise energy efficiency - Clean solar panels compared to dirty solar panels are more efficient in converting sunlight into electricity. Over time PV panels can reduce their effectiveness as the solar cells are unable to absorb solar energy, reducing their output when covered in dust, debris, bird droppings or staining, also referred to as 'hard shading'. Hard shading, refers to a fixed point of shade that blocks the light. Hard shading can also include the impact of air pollution, by being in a heavily polluted or urban area with industrial or car emissions can accumulate on solar panels, diminishing their efficiency. This differs from 'soft shading which is always on the move such as tree branches or shadows. Routinely cleaning solar panels, helps to ensure the panels get maximum exposure to sunlight and operate at optimal capacity.

3. Cost Saving - Having clean solar panels can also be cost-effective in a number of ways. Solar panels that are free from dust or debris can generate more electricity because they have more exposure to sunlight, resulting in higher energy production and reducing the reliance on grid power, cutting down your energy bill in the process.
Keeping your solar panels clean also reduces the maintenance involved and the need to regularly repair or replace panels which can be a costly expense. Regular cleaning in line with manufacturer's recommendations, can be a low-cost solution that preserves the efficiency and longevity of your solar panels, helping to save money in the long term.
Depending on a number of factors, such as where the panels are installed, climate and rate of debris, will all factor into how often the panels should be cleaned. Many solar panel suppliers and manufacturers recommend having your solar array cleaned, not only to maintain performance but as part of the warranty.
How do you clean solar panels?
Cleaning solar panels are an essential maintenance task to ensure their optimal performance. A professional service ensures your panels are cleaned to the highest of standards, as part of your manufacturing guidance.
Our professional and expert solar panel cleaning solution is a tailored service available nationwide and suitable for a range of premises, including domestic housing and commercial solar systems such as factories and warehouses. As part of our solar and panel cleaning service, our consultants carry out an onsite inspection survey, including looking at the level of access to the panels whether from the ground or roof access, and assessing your solar panel cleaning requirements.
Our solar panel cleaners use specially tailored equipment to efficiently clean your panels thoroughly and with accuracy. A high-pressure system such as a jet wash or blast cleaning can cause damage which is why a gentler approach is required. Our solar cleaner system uses a combination of consists of a pure water filter, water-fed poles and water-fed soft brush. Our extendable water-fed cleaning brushes are designed to feed purified water continuously, removing dirt, debris and bird droppings without damaging the surface panels. The non-abrasive brush uses a nozzle and hose on a long-handled pole to reach the panels and clean in a horizontal motion to clean and remove debris with ease without the need for harsh chemicals.
Frequently Asked Questions about Solar Panel Cleaning
-
Are solar panels designed to be self-cleaning?
It's a common misconception that solar panels are self-cleaning and require no cleaning. Many manufacturers and suppliers do offer solar PV panels with a hydrophobic coating, and it's this coating that acts as a barrier and stops water droplets and residue from sticking to the surface. But rainwater is not enough to ensure your panels are operating at a peak capacity as hard shading can still remain. We recommend that you speak to your solar panel installer for your specific solar panel system.
-
How much is it to clean solar panels?
Solar panel cleaning costs will depend on a number of factors, the number of solar panel arrays as more panels require more time to clean, the location of your panels and how easily accessible they are for example on the roof of your premises as this requires specialist materials and equipment to clean. To receive a free quote and on-site survey, please contact our team to book with one of our local experts.
-
Why do we use purified water?
The use of chemicals on photovoltaic (PV) panels can impact their functionality and can easily damage the panel, which can affect your installer's warranty. Purified water contains phenomenal cleaning power - without using chemicals whatsoever. Purified water means the panels will dry streak-free without any deposits and there is no requirement to wipe & polish the glass afterwards.
-
Can I clean my solar panels myself?
Whilst the task of solar panel cleaning may seem straightforward, there are a few aspects to consider to ensure safe and effective cleaning.
Safety Precautions: Safety should be your top priority when working with solar panels whether on the ground or roof. Ensure your personal safety by taking the necessary precautions. Whilst the risk of shock is minimal, a professional solar panel cleaning service will have access to specialist equipment to avoid the risk of electric shock.
Manufacturer's Guidelines: Before undertaking any maintenance or cleaning yourself, we would advise you to speak to a professional for advice and guidance on your solar panel system.
Accessibility and Ease of Cleaning: Assess your comfort level and expertise in handling and cleaning solar panels. There are a number of DIY solar panel cleaning kits available on the market but if you do not feel comfortable working at heights or with electrical components, a professional solar panel cleaning service eliminates the challenging aspects of cleaning with reliable results. Consider the time, effort, and potential risks involved in DIY clean compared to the cost of hiring a professional solar panel cleaner service.
